the oil is kinda funny it has about 15 minites on a fresh 5 1/2 quarts adn i drained it, the color is kinda dirty then clears up as it finishes draining, not white (milky). no white smoke while running, no white specs on spark plugs. but runs hot after 10 minutes, and i get quite a few drops of coolant out of the drain plug and the oil is watery
